Definitions

  • TITLE Keratin fibers shaping tool, and associated kits and method
  • the present invention relates to a tool for shaping keratin fibers.
  • compositions dedicated to makeup for keratin fibers aim to densify the thickness and the visual perception of the eyelashes or eyebrows and ultimately the look.
  • this use is not satisfactory because the coverage is ephemeral, and the curvature of the eyelashes returns to its natural state, once the mascara makeup is removed.
  • Another property that is especially sought by consumers is to obtain a significant curling of said keratin fibers that is persistent to successive makeup removals.
  • curling means a difference in angle between the chord before application, passing through the base of the keratin fiber, preferably of the eyelash, and by the tip of the chord after application, by at least 10°, preferably by at least 15°, preferably by at least 20°.
  • persistent curling means a curling that persists even after makeup removal. This persistent curling can last at least a few hours, preferably at least a few days.
  • the eye-curler generally consists of a clamp that can be actuated manually, the clamp clamping the eyelashes in order to curl them.
  • the eye-curler does not provide full satisfaction.
  • handling the eye-curler is delicate for the user.
  • the handling is accompanied by a repeated clamping of the eyelashes or maintained in a prolonged manner which can damage the eyelashes. Such damaged eyelashes break or are pulled out.
  • a purpose of the invention is therefore to provide a solution that makes it possible to provide a curling of keratin fibers, in particular the eyelashes, that is simple to use, without damage for the fibers and as durable as possible.
  • Another purpose is to ensure good separation of the fibers during the shaping.
  • the object of the invention is a tool for shaping keratin fibers comprising a gripping member extending along a longitudinal axis, and a shaping member comprising a base body and ribs, the base body being integral with the gripping member, and having two lateral edges, and extending from the gripping member to a free distal edge opposite the gripping member, the free distal edge joining the two lateral edges to one another, each rib extending protruding from the base body along a respective elevation direction, the ribs also extending parallel to one another and to a transverse axis and defining grooves between them, each rib having a constant height along the transverse axis between the two lateral edges of the base body, the free distal edge of the base body extending parallel to the transverse axis.
  • the tool according to the invention is indeed entirely adapted to the shaping of keratin fibers in a way that is easy to use and without damage for the fibers, without the constraints associated with usual applicators intended to apply a mascara composition.
  • the shape of the usual applicators intended for applying a mascara composition is indeed constrained by the usage thereof, in particular at the applicator that has to cooperate with a squeezing device able to control the volume of the composition loaded onto the applicator. The tool of the invention is thus released from these constraints to provide an optimal shape for shaping fibers.
  • this tool in particular at the distal edge of its shaping member, provides a useful zone over the entire length of the shaping member and minimizes the discomfort at contact with the corner of the eye, when the fibers are eyelashes.
  • the shaping tool according to the invention may include one or more of the following features, taken alone or in any technically possible combination:
  • the free distal edge of the base body stops at the rib that is farthest from the gripping member

  • a separation between the two lateral edges of the base body is constant along the base body, the separation being preferably comprised between 3.0 mm and 10.0 mm, advantageously between 7.0 mm and 9.0 mm;
  • each groove has a bottom formed by the base body and all the bottoms of the grooves follow a shape that has a main radius of curvature greater than or equal to 2.0 cm, in projection in a plane parallel to the longitudinal axis and perpendicular to the transverse axis;
  • the main radius of curvature is comprised between 1 cm and 10 cm in such a way that all the bottoms of the grooves follow a curved shape, or the main radius of curvature is such that all the bottoms of the grooves follow a planar shape;
  • the shaping member has at least one plane of symmetry perpendicular to the longitudinal axis;
  • each rib following the elevation direction is comprised between 1 .0 mm and 4.0 mm, preferably comprised between 2.0 mm to 3.0 mm;
  • each rib extends from the base body along a respective elevation direction up to a top, the separation between the tops of two adjacent ribs being constant and advantageously comprised between 0.3 mm and 5.0 mm, preferably comprised between 1 .0 mm and 2.0 mm;
  • each rib extends from the base body along a respective elevation direction up to a top, the distance between the tops of two ribs being the farthest from one another being comprised between 1 .0 cm and 5.0 cm, preferably comprised between 2.0 cm and 4.0 cm, advantageously comprised between 3.0 cm and 4.0 cm;
  • each rib has a shape with a triangular point, in a slot, or curved, in a cross-section perpendicular to the transverse axis.
  • the invention also relates to a cosmetic application kit comprising:

  • the present invention also relates to a makeup method for keratin fibers and an associated kit, allowing for a persistent curling of said fibers.
  • compositions dedicated to makeup for keratin fibers aim to densify the thickness and the visual perception of the eyelashes or eyebrows and ultimately the look.
  • another property that is especially sought by consumers is to obtain a significant curling of said keratin fibers that is persistent to successive makeup removals.
  • a makeup method inspired by permanent hair techniques that consists, firstly, in applying on the eyelashes a reducing composition comprising a reducing agent (for example ammonium thioglycolate and the derivatives thereof or thiol compounds) that break the disulfide bridges of the keratin of the eyelashes then, secondly, in applying an oxidizing composition comprising at least one oxidizing agent such as hydrogen peroxide to reestablish the disulfide bridges of the keratin of the eyelashes, shape the eyelashes and obtain a durable curling.
  • a reducing composition comprising a reducing agent (for example ammonium thioglycolate and the derivatives thereof or thiol compounds) that break the disulfide bridges of the keratin of the eyelashes then, secondly, in applying an oxidizing composition comprising at least one oxidizing agent such as hydrogen peroxide to reestablish the disulfide bridges of the keratin of the eyelashes, shape the eyelashes
  • Patent applications KR101823336 and KR101823401 propose a method for the semi-permanent curling of eyelashes comprising the application on the eyelashes of a mascara comprising at least one reducing agent such as cysteine, cysteamine, thiol compounds, sodium bisulfite, sodium metabisulfite, sodium hydrosulfite or superoxide dismutase, and at least one antioxidant such as a compound with a phosphoric acid base or a compound with a zinc, gold, tin or silver base, followed by a washing and a drying of the treated eyelashes.

  • a makeup method comprising a first application step on said keratin fibers of a composition comprising:
  • a second step of shaping said fibers by application on the latter of a shaping tool comprising a gripping member extending along a longitudinal axis X, and a shaping member comprising a base body and ribs, the base body being integral with the gripping member, and having two lateral edges, and extending from the gripping member to a free distal edge opposite the gripping member, the free distal edge joining the two lateral edges to one another, each rib extending protruding from the base body in a respective elevation direction Z, the ribs also extending parallel to one another and to a transverse axis Y and defining grooves between them.

  • the application of such a composition on the keratin fibers, in particularly the eyelashes, followed by the shaping of the fibers by the tool according to the invention makes it possible to curl said fibers in a persistent manner, and this, without using an oxidizing agent.
  • Such a method is easy to implement at home for the consumer.
